Given numbers are 405, 476, 945, 126

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 126 are 2 x 3 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 405, 476, 945, 126

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(405, 476) = 192780

GCD(405, 476) = ( 405 x 476 ) / 192780

= 405 / 476

= 405

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 405, 476, 945, 126 is 1
